' This invention relates to new and useful improvements in printing andmore particularly to a process and mechanism for producing a newspaperhaving certain of the pages distinctively tinted or colored, as well asto the novel product of the process. Objects and advantages of theinvention will be set forth in parthereinafter andinp-art will beobvious herefrom, or maybe learned 1o by practice with the invention,the same being realized and attained by means of the instrumentalitiesand combinations pointed out in the appended claims.

The invention consists in the novel parts, construction, arrangements,combinations and improvements herein shown and described.

The accompanying drawing, referred to herein and constituting a parthereof, illustrate one embodiment of the invention, and together withthe description, serve to explain the principles of the invention.

In the production of certain "editions of newspapers it has beencustomary, with many of the metropolitan dailies, toemploy one web ofpaper dyed a color different from that of the remaining webs therebyproduc- 5 ing a'product in which certain of the sheets are distinctivelycolored, for the purpose of identifying the particular edition. Thispractice necessitates carrying on hand a plu-' rality of diiferent kindsof paper-and, as gen- 1929. Serial in. 354,909.

which four of the pages are colored dilferently from the rest. Thepresent invention .is directed to the provislon of a printing press forproducing colored or tinted a distinctive color.

The general arrangement of the printing and folding units in the presentpreferred embodiment of the invention, exemplarily illustrated herewithas applied to a straight line rotary printing press, comprises, broadlyconsidered, a plurality of rotary printing couples for perfecting one ormore webs of paper, suitable associating, folding and cutting mechanism,and means for tinting or coloring a portion of one of the webs prior orsubsequent to the printin of the web.

According to the pre erred embodiment, means are also providedassociating a plurality of untinted webs with the tinted web I and forassociating and folding the printed and tinted web so as to place thetinted sheet outermost of the printed product. Means arealso providedfor variably positioning the tinting orcoloring means forcoloring otherpages than page one of the printed product. Means are also provided forsilencing the tinted means when it is not desired to produce a newspaperhaving a tinted page, and other means are provided for registering thetinted web with the impressions of the printing couples and forregisteringthe tinted and printed web with respect'to the folding andcuttin provi ed a drying means for dryln the web, as it passes throughthe press an .prior to the time it is printed. 'Means are also provided,for use when running collect runs, whereby only one page of thecollected product is tinted.

mechanism. Optionall. there is erally practiced, produces a newspaper inI The present invention also providesanovel mo ing couples.

It will be understood that the foregoing 'general description and thefollowing detailed description as well are exemplary and explanatory ofthe invention but are not restrictive thereof.

In the accompanying drawing illustrating the present preferredembodiment of the invention, the invention'is shown as applied toaconventional straight-line rotary printing press, although it canequally well be applied to other forms of press construction.

As shown, there are provided means for perfecting a plurality of. websof paper, and for folding, associating and cutting these webs to formnewspapers of varying size. As embodied, these means comprise aplurality of superposed rotary printing couples, each including a pairof cooperating printing and impression cylinders, 10 and 11, re-'spectively, for printing webs of paper 12, preferably four pages wide,which are fed from web rolls 13 and supplied to the print- Suitableinkin mechanism 14 is provided for each of the printing cylinders. Afterthe webs of paper are printed they are led under guide rollers 16,associated and fed to the folding mechanism, which in the presentinstance comprises a pair of formers 17, side by side, provided withfolding andcollecting cylinders 18, and cutting cylinders, in the usualmanner. When using a web four pages wide, slitters 20' may be employedto slit the web ust prior to its being fed over the formers 17, thusproducing two separate sections of the newspaper. d

When desired, all the webs can be passed over a single one'of theformers 17 and for this purpose, there are provided slitters 21 andturner bars 22, for each of the webs.

The printing cylinders 10 and impression cylinders 11 are preferablymade two pages in circumference .and, as is usual, the cut, associatedand folded sheets may be collected on the folding cylinder 18, ifdesired.

-' According to the present invention, there are provided cooperatingtinting or coloring meansfor coloring one or more, and preferably thefirst, pages of the products of the press, and as embodied, there isprovided a tinting mechanism for applying a tinting or coloring medium,suchas; ink, to a portion of the web of paper. In the presentembodiment, these tinting or coloring means com-- prise a cylinder 24having a substantially smooth surface, cooperating with a rotatableimpression cylinder 25 having a -resilient covering-.and mounted in thepress frame, so that one of the webs can. be passed' between the tintingand impression cylinders. Suitable inking means are provided, andcomprise an ink drum 26, fountain 27, distributing rolls color only thefirst page of the first section.

For accomplishing this purpose and for tinting alternate successivepages along one of" the webs, the tinting cylinder 24 is provided withremovable-semicylindrical shells 31 each having a smooth metal surface,so that alternate pages of the 'web roll will be left untinted.

The constructionof this cylinder is shown more in detail in Fig. 4,where the semi-cylindrical shells 31 are secured to the cylinder 24 bykeys'32 set in registering key-ways in the shells and cylinders. Whenonly the alternate pages are to be tinted, one of the shells is removed.To insure coloring the whole of the proper page, the shells are madewith abutting edges, and when both shells are in position on thecylinder, they substantially completely encircle the cylinder.

For moving the tinting mechanism from one side of the web to the other,in order to tint other pages than the first, the tinting cylinder 24 andand inking mechanism are, in the present embodiment-mounted as a unit ina supplemental frame variably positionable transversely of the web.-This supplemental frame may comprise side members 33 and 34, slidablealong supporting and guide rods 35 mounted in the press frame 36. Ashaft 37,

provided with a key way 38 is provided for driving the tinting cylinder.Any suitable means can be provided for holding the supplemental frame inany one of its several positions. g

For registermg the impression of the several couples with each other,with the folding for correcting minute variations in register suitablecompensators 39can beprovided between the tinting and printing units andbetween the printing couples and folding units. If desired,'means may beprovided for at least partially drying the tinting ink after it isapplied to the web and before the web is printed, and as here embodied,these means comprise adrier 40 capable of bloiving' a strong blast ofheated air onto the web "as it passes over roller 41.

For silencing the tinting-mechanism, when the edition does not requirethe use of the distinctively colored page, means are provided forwithdrawing the web from contact with the tinting cylinder 24. Asembodied, pressure roller 25 deflects the Web 12 out of its normal pathbetween rolls 41, 42, when the tinting mechanism is in use, and thesupporting shaft for pressure roller 25-is mounted in eccentric bushings43 which can be turned to space roller 25 away from .cylinder 24.

While shown as applied to a straightline press in which page 1 isprinted on the upper deck, it is, of course, obvious that the inventioncan be used with other types of printing presses such as those employinginverted folders, and unit-type presses. In the case of a unit-typepress, the tinting mechanism would be formed as a unit and would bemovable from one unit to another dependent on which unit is employed forprinting page one of the newspaper.

The invention in its broader aspects is not limited to the specificmechanisms shown and described but departures may be made therefromwithin the scope of the accompanying claims without departing from theprinciples of the invention and without sacrificing its chiefadvantages.
